Life Comparison - Compare Two Designs Using the Life Comparison Tool

Using the data presented in Example 1, use Weibull++'s Life Comparison tool to estimate the probability that units from the new design will outlast units from the old design.


Solution

After entering the data sets into two different folios (or two data sheets within the same folio) and analyzing them (in this case, the two data sets were analyzed using the two-parameter Weibull distribution and MLE), open the Life Comparison tool and select to compare the two data sets.

The next figure shows the pdf curves and the result of the comparison.
